Well... The cookies are baked and cooled. Almost. And since she's running late, she's leaving everything out on the counter - the bowls, the cookie sheets, the rolling pin, etc.... Along with a note on the fridge, "Sorry for the mess. I'll finish up baking when I get home tonight."
-Of course, she won't be back until 9:30pm. Seven and a half hours from now. Hmm...
Now, I really don't mind cleaning and washing dishes. Really I don't. And I don't ming being asked to clean up - especially if someone is on a tight schedule. That can happen. But to leave a mess on the counters and a note of the fridge while I'm sitting ten feet away... And she knows that I could be home all day... Well...

In any case, I'll clean up. Heck, it's something to do. And with all the sprinkling sugar that ended up on the floor, I need to sweep that up before the ants come back. And they will come back.
